Title: Method forming multilayer interconnection
Inventor: SHINGU MASATAKA
IPC: H01L21/3205
Filed: 1986-10-28
Abstract: PURPOSE:To prevent the formation of steps attributable to the chipping of an SiO2 lower layer during an etch-back process for the formation of side walls by a method wherein the side walls are built of Al. CONSTITUTION:After the patterning of a first Al-Si layer 1, a plasma Si3N4 film 3 is grown. The Si3N4 film 3 serves as a stopper in an etchback process and, simultaneously, is effective in preventing the formation of hillocks in the first Al-Si layer 1. Next, a second Al-Si layer 4 is formed, which is subjected to etch-back, after which side walls are retained on the step in the Al-Si layer 4. With the gas etching rate being very low against the plasma Si3N4 film, the lower-layer Si3N4 film is never to be chipped because of excess etching in an RIE etch-back process. When this technique is employed, a lower layer is never to experience excess etching, which eliminates the possibility of the formation of steps.

Abstract: PURPOSE:To remove an unnecessary side band wave without using a filter and to maintain wide the band of a carrier chrominance signal by demodulating the carrier chrominance signal to perform a chrominance signal processing, sample-holding, and thereafter modulating into a prescribed carrier chrominance signal. CONSTITUTION:A demodulator 2 is a circuit for operating with a clock frequency of 1/8fs with respect to the clock frequency of a processing system, thereby generating a spectrum every 1/8fs including a base band area chrominance signal in the band area of fs. Two color difference signals obtained by the demodulation are passed through sample hold circuits 7, 8 by switches 5, 6 connected to terminals 52, 62 during recording and connected to terminals 51, 61 during reproducing. Since the sample hold circuit operates the clock frequency as fs again, the spectrum of the chrominance signal appears similarly to the output of the demodulator 2 at the interval of 1/8fs, and when output data is held in a cycle of 1/8fs, a bottom is present in the frequency integer times as large as a hold frequency and a gain of the pass area is attenuated, the frequency characteristic of a zero order hold, what is called, is obtained and a high harmonic wave component except for a base band signal component is attenuated.
